Title: Laccases with improved dyeing properties
FIELD OF THE lNvL.~lON
The present invention relates to a dyeing composition
comprising a microbial laccase, the use of said dyeing
composition for dyeing keratinous fibres, in particular hair,
fur, hide and wool, and a method for dyeing keratinous fibres.
0 R~CK~-R~uND ~F THE lNv~,.~lON
It has been used for many years to dye the hair to cover
appearing grey hair. The need to do so arises from the fact
that grey hair is the first sign of having past adolescence,
which can be hard to accept for many people.
For instance, in certain parts of Asia it is widely used by
both men and women to dye the hair with dyes often referred to
by humorous people as "black shoe polish".
During the last few decades hair dyeing has become more and
more popular in the western world. At first Punk Rockers and
other society critical groups dyed their hair in exLL~ ~
colours as a part of their protest against the established
society, but today especially many young people also uses hair
dyes (in more soft tints than the Punk Rockers) as a sort of
"cosmetic" to change or freshen up their "look".
Hair dyes
In general hair dyeing compositions on the market today can
be divided into three main groups:
- temporary hair dyes,
- semi-permanent hair dyes, and
- permanent oxidative hair dyes.
The temporary hair dyes are only intended to change the
natural hair colour for a short period of time and usually
functions by depositing dyes on the surface of the hair. Such
hair dyes are easy to remove with normal shampooing.
When using semi-permanent hair dyes the colour of the dyed
hair can survive for five or more shampooings. This is achieved
~UBSTn~TESHEET
CA 02238697 1998-0~-27
W O 97/19999 PCTADK9~/00499
by using dyes having a high affinity for hair keratin and which
i5 able penetrate into the interior of the hair shaft.
Permanent hair dyes are very durable to sunlight, shampooing
and other hair treatments and need only to be refreshed once a
month as new hair grows out. With these dyeing systems the dyes
are created directly in and on the hair. Small aromatic colour-
less dye precursors (e.g. p-phenylene-diamine and o-
aminophenol) penetrate deep into the hair where said dye
precursors are oxidised by an oxidising agent into coloured
polymeric compounds. These coloured compounds are larger than
the dye precursors and can not be washed out of the hair.
By including compounds referred to as modifiers (or
couplers) in the hair dyeing composition a number of hair
colour tints can be obtained. Cathecol and Resorcinol are
examples of such modifiers.
Tradit;o~lly H2~2 is used as the oxidizing agent ~colour
builder), but also as a bleaching agent. Dyeing compositions
comprising H2~2 are o~ten referred to as "lightening dyes" due
to this lightening e~fect of H202.
The use ~f H202 in dyeing compositions have some
disadvantages as H2~2 damages the hair. Further, oxidative
dyeing often demands high pH (normally around pH 9-10), which
also in~licts damage on the hair and on the skin. Consequently,
if using dye compositions comprising H2~2 it is not recommend-
able to dye the hair o~ten.
To overcome the disadvantages o~ using H2O2 it has been sug-
gested to use oxidation enzymes to replace H2O2.
US patent no. 3,251,742 (Revlon) describes a method for
dyeing human hair by dye formation in situ (i.e. on the hair).
An oxidative enzyme is used to the colour formation reactions
at a substantially neutral pH (7-8.5). Laccases, tyrosinases,
polyphenolases and catacolases are mentioned as suitable
oxidation enzymes. The only exemplified oxidation enzyme is
tyrosinase.
EP patent no. 504.005 (Perma S.A.) concerns dyeing
compositions for keratinous fibres, in particular hair, which
do not require the presence of H2~2 (hydrogen peroxide). The
SUBSTn~mESHEE~
CA 02238697 1998-0~-27
W O 97/19999 PCT~DK96/00499
composition comprises an enzyme capable of catalysing the
formation of the polymeric dyes and also dye precursors, such
as bases and couplers, in a buffer solution wherein the pH of
said composition is between 6.5 and 8 and said enzyme has an
optimal activity in the pH range between 6.5 and 8.
Rhizoctonia praticola laccase and Rhus vernicifera laccase
are the only laccases exemplified in the patent.

SUNMARY OF T~ lN V h~ ~lON
The object of the present invention is to provide improved
dyeing compositions for keratinous fibres, such as hair, fur
hide and wool, comprising an oxidative enzyme as the oxidising
agent.
In the context of the present invention an l-improved"
composition for dyeing keratinous fibres means a composition
being capable of dyeing the keratinous fibres in ~uestion
faster or by the use of a smaller amount of oxidation enzyme to
obtain an optimal dyeing effect, determined as ~F*, in
comparison to corresponding prior art dyeing compositions.
Further, it is also possible to use a less amount of dye
precursor. This is advantageous as certain dye precursors are
very unhealthy and very carcinogenic.
Compositions capable of dyeing the keratinous fibres, in
particular hair, fur, hide and wool, faster are desirable as
such compositions are very user convenient.
Further, it is desirable to be able to use a less amount of
enzyme in the dyeing composition. This might make the dyeing
process more economical. Further, the risk for creating
airborne protein aerosols is reduced.
It has now surprisingly been found that it is possible to
provide such improved dyeing compositions for keratinous fibres
by using microbial laccases for oxidising the dye precursor(s).
Laccases (benzenediol:oxygen oxidoreductases) (E.C. class

1.10.3.2 according to Enzyme Nomenclature (1992) Academic
Press, Inc.) are multi-copper containing enzymes that catalyse
the oxidation of phenols. Laccasc -~;ated oxidation results in
the production of aryloxy-radical intermediates from suitable
phenolic substrates; the ultimate coupling of the intermediates
so produced provides a combination of dimeric, oligomeric, and
polymeric reaction products. Certain reaction products may be
used to form dyes suitable for dyeing keratinous fibres, such
as hair and wool (see below).
Firstly, the object of the invention is to provide a dyeing
composition comprising
a) above O to 1 mg enzyme protein per ml dyeing composition of
microbial laccase,
b) one or more dye precursors,
c) optionally one or more modifiers.
Specifically contemplated is laccases of microbial origin,
derived from a strain of the genus Myceliophthora.
In the second aspect the invention relates to the use of a
dyeing composition of the invention for dyeing keratinous
fibres, such as hair, fur, hide and wool.
The invention also related to a method for dying keratinous
fibres comprising contacting the dyeing composition of the
invention to the keratinous fibres in question under suitable
conditions and for a period of time sufficient to permit
oxidation of the dye precursor into a coloured compound.
The invention also relates to the use of a laccase for
permanent dyeing of keratinous fibres wherein said laccase is a
laccase that results in a ~E*-value higher than the AE*-value
resulting from a laccase derived from Rhus under corresponding
dyeing conditions.
This means that when dyeing keratinous fibres with a dyeing
composition of the present invention the ~E*-value determined
are higher than the ~E*-value det~rm;ned from corresponding
keratinous fibres dyed under the same conditions using a dyeing
composition comprising a laccase derived from Rhus.
The term "corresponding dyeing conditions" means under
conditions where e.g. the enzyme concentration or enzyme
SUBSTnUTES~tl
CA 02238697 1998-0~-27
WO 97/19999 PCT~DK96/00499
activity, dyeing incubations time, dyeing incubation tempera-
ture, pH conditions, keratin fibre type (such as hair type) are
the same, and further that the same dye precursor(s) and
modifier(s) are used. In other words it defines conditions
parallel to the specific dyeing conditions chosen. The dyeing
conditions described below in the Examples may be chosen.
In the context of the present invention a "higher'l ~E* value
defines that the total quantitative colour change is more than
one ~F* unit.
~E* is calculated from the values of the parameters a*, b*
and L* determined e.g. on a Minolta CR200 Chroma Meter using
the formula ~E*= ~(~L*2~a*2+~b*2). The ~n;ng of a*, b* and L*
is explained below in the "Materials and Methods" section.

The object of the present invention is to provide improved
dyeing compositions for permanent dyeing of keratinous fibres,
such as hair, fur, hide and wool, comprising an oxidation
enzyme.
It has now surprisingly been found that it is possible to
provide such improved dyeing compositions by using a microbial
laccase for oxidising the dye precursor(s).
Thç DYeinq Composition
In the first aspect the present invention relates to a
dyeing composition comprising
a) above 0 to 1 mg enzyme protein per ml dyeing composition of
microbial laccase,
b) one or more dye precursor, and
c) optionally one or more dye modifiers.
In a preferred em~odiment of the invention the laccase may
be present in the dyeing compositions in a concentration within
the range from 0.0001 to 1 mg/ml, preferably 0.001 to 0.8
mg/ml, more preferred 0.002 to 0.5, even more preferred 0.003
to 0.2, especially 0.004 to 0.1 mg enzyme protein/ml dyeing
composition.
When dyeing with a composition of the invention for
permanent dyeing the ~*-value obtained is higher than that
obtained ~hen using a dyeing composition comprising a laccase
derived from Rhus under corresponding dyeing conditions.
An example of a Rhus laccase is the laccase derived from the
Japanese varnish tree Rhus vernicifera (Yoshida, (1883), J.
Chem. Soc., 472). The Rhus vernicifera laccase is used in the
3~ Example 1 below.
The microbial laccase used according to the invention is of
fungal or bacteria origin, in particular of filamentous fungus
origln .
In an embodiment of the invention the microbial laccase is
derived from a strain of genus Myceliophthora, such as a strain
of the species Myceliophthora thermophila e.g. the purified
laccase described in W0 95/33836 (PCT/US95/06815) from Novo

Nordisk, which is hereby incorporated by reference. SEQ ID NO 1
below shows a DNA sequence encoding a suitable laccase
~ derivable from Myceliophthora thermophila.
E. coli JM101 cont~;ning the expression vector pRaMB~ com-
prising SEQ ID NO 1 has been deposited under the BudapestTreaty with the Agricultural Research Service Patent Culture
Collection, Northern Regional Research Center, 1815 University
Street, Peoria, Illinois, 61604. The vector have been given the
Accession Number NRRL B-21261.
Also contemplated according to the invention are laccases
derived from other micro-org~n;s~ being more than 80% homo-
logous to SEQ ID NO 1 derived from Myceliophthora thermophila.
In addition, Myceliophthora laccases also encompass alterna-
tive forms of laccases which may be found in M. thermophila and
as well as l~cc~es which may be found in other fungi which are
synonyms of fall within the definition of M. thermophila as
described by Apinis (Nova Hedwigia 5, 57-78, 1963) and named
Sporotrichum thermophile. Subsequent taxonomic revisions have
placed this organism in the genus Chysosporium (Von Klopotek,
20 A. Arche., (1974) Microbiol, 98, 365-369) and later Myceliopht-
hora (Van Oorshot, Persoonia, (1977), 9, 401-408). A number of
organisms known by other named also appear to belong to this
species. These include Sporotrichum cellulophilum (US patent
no. 4,106,989); Thielavia thermophila (Fergus and Sinden
25 (1968), Can. ~. Botany, 47, 1635-1637); Chrysosporium ~ergussi
and Corynascus thermophilus (Von Klopotek, supra).
Also the use of laccase variants are contemplated according
to the present invention.
An example of a laccase variant is the Myceliophthora ther-
30 mophila T1 variant described in PCT/US96/14087 (Novo Nordisk).
T1 variants (or Type I variants) are modified blue copper
oxidases, including laccases. T1 variants can for instance be
constructed by site-directed mutagenesis and differ ~rom the
- corresponding wild-type blue copper oxidases by at least one
3~ amino acid residue in the Type I (T1) copper site. These modi-
fications generally result in altered pH profiles and/or
specific activity relatively to the wild-type enzymes. This can
SUBSTITUrE SHEEI
CA 02238697 l998-0~-27
WO 97/l9999 PCT~K96/00499
be advantageous when using the enzyme in question in dyeing
compositions.
More specific the Myceliophthora thermophila T1 laccase
variant may comprise the sequence 509VSGGL511 or may be
modified as to increase the negative charge in at least one
segment of the T1 copper site.
The above mentioned microbial laccases may advantageously be
used in permanent dyeing composition for keratinous fibres.
Such compositions have a superior dyeing effect to
10- corresponding compositions comprising e.g. the ~hus vernicifera
laccase as shown in Example 1.
The Myceliophthora thermophila T1 variant laccase is more
wash stabile and further dyes faster than the Polyporus pinsi--
tus laccase which is proven in Example 2 and Example 3, respec-
tively.
Example 4 shows that less Myceliophthora laccase activity
(i.e. LACU/ml) is needed to obtain a suitable dyeing effect in
comparison to the Polyporus pinsitus laccase.
Example 5 shows that for the Myceliophthora thermophila
laccase the dyeing effect optimum is obtained around 0.005 mg
enzyme protein per ml dyeing composition.
In the case of using a Myceliophthora laccase in a permanent
dyeing composition it may advantageously be present in
concentrations from above 0 to l mg/ml, preferably O.O001 to
2~ 0.1 mg/ml, more preferably 0.0005 to 0.05 mg/ml, especially
O.001 to O.01 mg enzyme protein per ml dyeing composition.
It is to be understood that the laccase may be produced
either homologously, or heterologously in a host cell such as
f1l~-ntous fungus, yeast or bacteria.
~xamples of f;l~ entous fungi host cells include strains of
the species of Trichoderma, preferably a strain of Trichoderma
harzianum or 'I'richoderma reesei, or a species of Fusarium, or a
species of Aspergillus, most preferably Aspergillus oryzae or
Aspergillus niger, or yeast cells, such as e.g. a strain of
Saccharomyces, in particular Saccharomyces cerevisiae, Saccha-
romyces 7~luyveri or Saccharomyces uvarum, a strain of
Schizosaccharomyces sp., such as Schizosaccharomyces pombe, a
SUBSTITUrE S~IEET

strain of ~ansenula sp., Pichia sp., Yarrowia sp., such as
Yarrowia lipolytica, or Rluyveromyces sp., such as Kluyveromy-
ces lactis, or a bacteria, such as gram-positive bacteria such
as strains of Bacillus, such as strains of B. subtilis, B. Li-
cheniformis, B. lentus, B. brevis, B. s~earothermophilus, B.alkalophilus, B. amyloliquefaciens, B. coagulans, B. circulans,
B. lautus, B. megaterium or B. thuringiensis, or strains of -
Streptomyces, such as S. lividans or S. murinus, or gram-nega-
tive bacteria such as Escherichia coli.
To obtain dyeing of the keratinous fibres the dyeing compo-
sition of the invention comprises one or more dye precursors
which is(are) converted into coloured compound(s) by an oxida-
tion agent which according to the present invention is a
microbial laccase.
Without being limited thereto the dye precursor(s) may be
(an) aromatic compound(s) belonging to one of three major
chemical families: the diamines, aminophenols (or amino-
naphtols) and the phenols. Examples of isatin derivative dye
precursors can be found in DE 4,314,317-Al. Further, a number
of indole or indoline derivative dye precursors are disclosed
in WO 94/00100. Said dye precursors mentioned in these
documents are hereby incorporated herein by reference.
Examples of suitable dye precursors include compounds from
the group comprising p-phenylene-diamine (PPD), p-toluylene-di-
amine (PTD), chloro-p-phenylene-~;~m;ne, p-aminophenol, o-ami-

20- In an embodiment the laccase is used with the dye precursor
directly to oxidise it into a coloured compound. The dye
precursor may be used alone or in combination with other dye
precursors.
It is believed that when using a ~;~ine or an aminophenol
as the dye precursor at least one of the intermediates in the
co-polymerisation must be an ortho- or para-diamine or amino-
phenol. Examples of such are found below and are also described
in US patent no. 3,251,742 (Revlon), the contents of which are
incorporated herein by reference.
Optionally dyeing compositions (especially hair dyeing com-
positions) of the invention also comprise a modifier (coupler)
by which a number of colour tints can be obtained.
In general modifiers are used in dyeing composition for hair as
the hair colours resulting from hair dyeing compositions
without modifier(s) are usually unacceptable for most people.
Modifiers are typically m-diamines, m-aminophenols, or poly-
phenols. Upon the optional addition of a modifier (coupler) it
~UBSTIT~TES~EET

reacts with the dye precursor(s) in the presence of e.g. a lac-
case, converting the dye precursor(s) into a coloured compound.
- Examples of modifiers (couplers) include m-phenylene-diami-
ne, 2,4-diaminoanisole, l-hydroxynaphthalene(a-naphthol), 1,4-
dihydroxybenzene(hydroquinone), 1,5-dihydroxynapthalene, 1,2-
dihydroxybenzene(pyrocatechol), 1,3-dihydroxybenzene (resorci-
nol), 1,3-dihydroxy-2-methylbenzene, 1,3-dihydroxy-4-chloroben-
zene(4-chlororesorcinol), 1,2,3,trihydroxybenzene, 1,2,4-trihy-
droxybenzene, 1,2,4-trihydroxy-5-methylbenzene, 1,2,4-trihydro-
xytoluene.
When using the dyeing compositions of the invention areduced amount of enzyme (i.e. mg enzyme protein per ml dyeing
composition) is n~erl to obtain the ~x; -l dyeing effect (See
Figure 1 and Figure 4), determined as the optimal ~E*-value, in
comr~ison to prior art dyeing compositions, such as dyeing
compositions comprising a laccase derived from ~hus.
The amount of dye precursor(s) and other ingredients used in
the composition of the invention are in accordance with usual
c~ ~rcial amounts.
According to the invention the product comprising the dyeing
composition may be a one or a two compartment product. In the
one compartment product the laccase, the dye precursor(s) and
other ingredients are keep together in a stabilised solution or
kept under stable conditions (i.e. the dye precursors are not
oxidised by the laccase). In a two compartment product the lac-
case and the dye precursor(s) and other ingredients are keep in
two containers keep apart. The contents of said cont~; n~s are
mixed ; ~~iately before use.
USE
In the second aspect the invention relates to the use of the
dyeing composition of the invention for permanent dyeing of ke-
ratinous fibres, in particular hair, fur, hide and wool.
When using a dying composition of the invention the ~E*-
value obtained is higher than that of a dyeing composition com-
prising a laccase derived from genus Rhus under corresponding
dyeing conditions (see Figure 1).

Method
In the third aspect the invention relates to a method for
permanent dying of keratinous fibres comprising contacting a
dyeing composition of the invention with the keratinous fibres
in question under suitable conditions and for a period of time
sufficient to permit oxidation of the dye precursor into a
coloured compound.
The dyeing procedure may be carried out at room temperature,
preferably around the optimal temperature of the enzyme, typi-
cally with from 10 to 60~C; at a pE in the range from 3 to 10,preferably 5 to 9, especially 6 to 8; for a period of time be-
tween 10 and 60 minutes, preferably 15 to 50 minutes,
especially 20 to 40 minutes.
When using the method of the invention the ~E*-value
obtained is higher than that of corresponding methods where a
laccase derived from a strain o~ the genus Rhus are used under
the same dyeing conditions, in the presence or a~sence of at
least one ~odifier, with at least one dye precursor, for a pe-
riod of time, and under conditions su~ficient to permit
oxidation of the dye precursor used for oxidising the dye.
The method can be conducted with one or more dye precursors,
either alone or in combination with one or more modifiers.

Minolta CR200 Chroma Meter
~etermination of Laccase Activity (LACU)
Laccase activity is determined from the oxidation of syrin-
galdazin under aerobic conditions. The violet colour produced
is photometered at 530 nm. The analytical conditions are 19 mM
syringaldazin, 23.2 mM acetate buffer, p~ 5.5, 30~C, 1 min. Re-
action time.
1 laccase unit tLACU) is the amount of enzyme that catalyses
the conversion of 1.0 micromole syringaldazin per minute at
these conditions.
Assessment of the hair colour
The quantitative colour of the hair tresses is determined on
a Minolta CR200 Chroma Meter by the use the parameters L*
("0"=black and "100"=white), a* ("-"=green and "+"=red) and b*
("-" blue and "+" yellow).
~ L*, ~a* and ~b* are the delta values of L*, a* and b* re-
spectively compared to L*, a* and b* of untreated hair (e.g.
~L* = L*sa~nple ~ L*untreated hair)-
~E* is calculated as ~E*=~(~L*2+~a*2+~b*2) and is an
expression for the total quantitative colour change.
